DS1 Green

What DS1 Green does

DS1 Green is a Lithuanian electrical-infrastructure services provider established in 2021 as a renewable-energy-focused sub-brand of the DS1 Group, a European energy-infrastructure operator founded in 1991 and active across nine countries. The company specializes in the design, installation, and commissioning of grid connections up to 35kV for utility-scale solar parks, wind farms, battery energy storage systems (BESS), and commercial real-estate developments. It holds ESO-approved fast-track contractor status with Lithuania's distribution system operator, a credential that qualifies it to deliver accelerated utility-side connections and effectively functions as a market-access license in the Baltic grid-connection market.

The firm's technical offering covers the full connection lifecycle — from network-application design through to energization — using VERT-certified installation methodologies required for utility acceptance. Its customer base consists primarily of Baltic renewable-energy developers, with named engagements involving Evecon, Green Genius, and Elektrum Lietuva across projects ranging from 4.5 MW solar parks to 87 MW utility-scale developments and BESS installations. Headcount sits in the 11–50 employee range and operations are headquartered in Vilnius, Lithuania.

The business model is project-based, with revenue tied to the engineering, equipment, and installation scope of individual grid-connection contracts. The company does not appear to own or operate energy assets; instead, it monetizes the specialized labor, certification, and ESO-relationship required to connect third-party renewable assets to the Lithuanian distribution network. There are no disclosed funding rounds, M&A activity, leadership changes, or proprietary technology developments in the available record, and the parent DS1 Group structure provides cross-border operational reach that the sub-brand has not yet visibly leveraged outside Lithuania.

Others

• Litgrid: Lithuanian transmission system operator that interfaces with DS1 Green's distribution-level ESO work; not a direct competitor but a key counterpart/customer ecosystem player for high-voltage renewable connections.

Emerging players

• Aarsleff (Per Aarsleff Holding): Listed as a client of DS1, Aarsleff is a Nordic infrastructure contractor with growing activity in Baltic energy infrastructure, including cable and substation works—a potential peer or partner competitor.

Direct peers

• Eltel Group: Nordic-headquartered power and communication infrastructure contractor serving DSOs/TSOs across Northern Europe. Direct peer in substation construction, cable laying, and renewable grid connections for utilities.
• Empower (Empower OÜ): Estonian/Baltic electrical infrastructure contractor delivering substation and grid-connection services to DSOs and renewable developers in the region—closest direct competitor geographically and operationally.
• Infratek (now part of Eltel): Historical Nordic/Baltic electrical infrastructure contractor specializing in substations and grid connections. Functionally analogous to DS1 Green, now consolidated within Eltel but a useful comparable for scope.

Broad incumbents

• Schneider Electric: Major provider of electrical distribution equipment, substation automation, and grid-tie solutions for renewable developers. Competes with DS1 Green on the equipment/integration layer of utility-scale connections.
• Siemens Energy: Global grid technology and EPC provider offering substation integration, protection/relay systems, and turnkey renewable grid connections—overlaps with DS1 Green's switchgear modernization and 35kV integration scope.
• Hitachi Energy (formerly ABB Power Grids): Global leader in substations, transformers, and grid integration technologies. Directly competes in the design, protection, and EPC delivery of substations connecting solar/wind farms to distribution networks.
• Vinci Energies / Omexom: Large European EPC/infrastructure group with an Omexom brand dedicated to energy infrastructure including renewable grid connections and substations. Competes for the same utility-scale solar/wind connection projects.
